Two leach-resistant waste forms, a borosilicate glass developed for the high-level waste calcines from reprocessed uranium fuels and iron-enriched basalt, a fused ceramic developed for americium plus plutonium wastes, have been leach tested. The specimens were leached in distilled deionized water and in a saturated salt brine at ∼30°C for 28, 63, and 126 days; one set was leached in a gamma field of ∼104 Gy/h (∼106 rad/h). The specimens were simulated high-level waste forms prepared from inactive ingredients and spiked with 22Na, 60Co, 95Zr-95Nb, 137Cs, 133Ba, 144Ce, and 241Am. The components were melted and heat treated, and specimens were sawed from the solidified material. The gamma field increased the leach rates in water (pH ∼3 after irradiation) typically by a factor of ∼10 and increased the leach rates in salt brine (pH decreased much less during irradiation) by a factor of ∼2. The leach rate of cobalt from glass was about seven times that from iron-enriched basalt. The leach rates usually decreased with increasing leach time. Both waste forms were still leach resistant in irradiated brine at 30°C, <2 µg/cm2·day, and fairly leach resistant in irradiated water at 30°C, <25 µg/cm2·day.
